The aim of this paper is the analysis of teenage consumers with varying degrees of healthy and unhealthy lifestyle habits and different healthy and unhealthy eating behaviours and food involvement, and its effects on packaging cues. At the same time, the paper tries to analyse the moderating role of gender.

With a sample of 589 (316 girls and 273 boys) young consumers (14–17 years old) and using SEM methodology, this paper tested a theoretical model related to the association between health, food, packaging cues and gender differences.

Among teenagers, healthy habits (sports) and healthy eating behaviours affect positively food involvement (p < 0.01 in both cases), and food involvement is positively related to informative packaging cues (p < 0.05). There are some differences between girls and boys. For example (1) there is a significant relationship between your consumers' sports activities and food involvement, and young consumers' healthy eating behaviours and food involvement. (2) More food-involved teenagers are those consumers that significantly read more carefully the packaging labels. Or (3) gender could be considered as a variable able to moderate the relationships between health and unhealthy lifestyle habits and eating behaviours, food involvement and packaging decisions.

The present paper tries to fulfil some literature gaps by developing a study with teenage consumers to solve three main questions/objectives: (1) Do healthy behaviours affect teenagers' food involvement? (2) Does teenagers' food involvement affect teenagers' packaging perceptions? and (3) Do girls and boys differ in their food packaging perceptions?

University students are a unique population with great potential to adopt eating habits that promote positive human and planetary health outcomes. The purpose of this study is to illustrate the current perceptions of sustainable eating behaviours among the students and to examine the determinants of sustainable eating behaviours.

Data were collected from December 2020 to May 2021 through focus group discussions among university students in Ontario, facilitated through synchronous online sessions. There were 21 student participants during the course of five focus group sessions (4–5 participants per session) from various departments within the university. The discussions were transcribed and analyzed for main themes and concepts using open coding; deductive coding based on the framework by Deliens et al. as well as the literature; and inductive coding for emerging themes.

The students had different perceptions about what constituted sustainable eating behaviours, some of which were not based on fact. A variety of individual, environmental (macro, micro and social) and university characteristics were mentioned as factors influencing sustainable food choices, with “food literacy” and “campus food” being the top two factors.

This study presents a novel and holistic overview of how sustainable eating behaviours and sustainable foods are perceived among university students and identifies the perceived determinants of adopting sustainable eating behaviours. This study helps with identifying opportunities to promote sustainable eating behaviours among university students and the design/implementation of informed interventions and policies aimed at improving eating behaviours.

With the improvement of consumers' health consciousness, healthy food has attracted great attention in daily consumption. Previous research into the sense of power often distinguishes it into high and low level, ignoring the impact of different construal of power on consumption behaviors. This article divides power into dual construal (responsibility vs opportunity) and aims to examine the differential impacts of the construal of power on healthy food preference.

Two pretests and three formal experiments were conducted to examine the effect of the construal of power on the consumer's healthy food preference, the mediation of self-discipline perception and the moderation of the relative strength of prevention over promotion focus (i.e. RSPPF).

Results indicate that individuals who construe power as responsibility (vs opportunity) exhibit higher self-discipline perception, which in turn leads to greater healthy food preference. However, the main effect above can be weakened among the low-power group. Moreover, the above mediating effect of self-discipline perception is stronger for individuals with higher RSPPF.

First, based on the binary-construal perspective, this study refines the classification of high power and introduces it into the antecedent research of healthy food preference. Second, this paper reveals the self-discipline perception as the inner mechanism underlying the effect of the construal of power on healthy food preference, while RSPPF as the boundary condition for this mediating mechanism. Moreover, this research also provides practical implications for healthy food enterprises that the construal of power, self-discipline perception and regulatory focus should be taken into consideration in advertising design and healthy product promotion.

As technology increasingly integrates into the restaurant industry, avatar servers present a promising avenue for promoting healthier dining habits. Grounded in the halo effect theory and social comparison theory, this study aims to delve into the influence of avatars' appearance, humor and persuasion on healthier choices and customer satisfaction.

This paper comprises three experimental studies. Study 1 manipulates avatar appearance (supermodel-looking vs normal-looking) to examine its effects on perceived attractiveness, warmth and relatability. These factors influence customer satisfaction and healthy food choices through the psychological mechanisms of social comparison and aspirational appeal. Studies 2 and 3 further refine this theoretical model by assessing the interplay of appearance with humor (presence vs absence) and persuasion (health-oriented vs beauty-oriented), respectively.

Results suggest that avatars resembling supermodels evoke stronger aspirational appeal and positive social comparison due to their attractiveness, thus bolstering healthier choices and customer satisfaction. Moreover, humor moderates the relationship between appearance and attractiveness, while persuasion moderates the effects of appearance on social comparison and aspirational appeal.

This research bridges the halo effect theory and social comparison theory, offering insights enriching the academic discourse on technology’s role in hospitality.

The findings provide actionable insights for managers, tech developers and health advocates.

Despite its significance, avatar design research in the hospitality sector has been overlooked. This study addresses this gap, offering a guideline for crafting attractive and persuasive avatars.

Health is an essential issue in the motivation to eat organic food. The aim of the study is to investigate the relationship if people who have a positive view of a healthy lifestyle (want to live healthy) have an influence on the tendency to buy organic food.

The analysis of secondary data dealing with the issue was supplemented by primary data. In order to meet the main aim, a preliminary objective was set which was to determine the influence of socio-demographic factors on the recommended lifestyle. Specifically, the largest statistically significant difference in influence on healthy lifestyle was gender, followed by education and age. The survey was conducted in the period of January–May 2019 on a sample of 1,373 respondents from Slovakia.

The data was evaluated by means of selected specific statistical methods (Kruskal–Wallis test, Man-Whitney test and Decision tree methodology). The results of the research verified that the lifestyle of Slovak consumers has an influence on the consumption of organic products and that people who practise healthy eating buy organic food more often. Our research has shown that lifestyle is increasingly influencing consumer purchasing behaviour.

The results showed that today's healthy lifestyle increases the demand for healthy food among potential consumers. Furthermore, the presented results of our research in Slovakia could establish some basis for conducting similar research in other European countries.

People often look to the opinions and actions of others to guide their food choices, especially when they are uncertain or unfamiliar with a particular food. This influence can be positive or negative depending on the context and can have an impact on food consumption and health outcomes.

The paper analysed data from 500 young adult consumers in China and employed a multi-study design to examine various aspects of social proof and herd behaviour in food choices. Experiment 1 examined the influence of testimonials from an influential person on buying decisions and eating behaviour. Experiment 2 explored whether herd behaviour drives food options. Experiment 3 assessed the influence of social proof on food choices. Chi-square tests of independence were conducted to examine the relationship between social proof and food choice, as well as herd behaviour and food decision-making. Several logit regression analyses were performed to identify the factors that drive consumers' susceptibility to social proof and herding.

The results indicated that the source of feedback, whether from an influential person or a family member, did not have a statistically significant effect on the likelihood of following the food guide recommendations. The preference for a healthier food option was stronger than following the herd. In contrast, social proof in the form of reviews and ratings influenced participants' choices. The paper highlights the usefulness for stakeholders and policymakers seeking to promote healthier eating habits.

The originality lies in its comprehensive approach, combining multiple experiments and analytical methods.

This research aims to elucidate why consumers decide to eat meals that seem to be higher in calories and salt, despite their goal being to consume fewer calories and sodium. Korean participants are to be used for this study. The present research further investigated the impacts of categorization and averaging bias in relation to the health halo phenomenon, specifically focusing on traditional food and textured vegetable protein (soy meat) burgers. Thus, the present research investigated how consumers' intentions contrasted with their consumption goals in food choice circumstances.

We partitioned the survey due to the COVID-19 epidemic. A single, well trained surveyor first surveyed customers at cafés in Seoul and six other Korean cities. We received 102 in-person survey replies. A total of 254 advanced degree or undergraduate students from two universities completed an online questionnaire. There are 356 responses. Two studies were conducted where participants were instructed to evaluate the perceived healthiness, calorie content, and sodium level of different food items. The specifics of each study are elucidated in the main body of the paper.

This study shows that Koreans categorize meals as virtue or vice depending on their perceived healthiness, validating the categorization effect. Furthermore, this research demonstrated that consumers' perceptions of the health benefits of traditional meals and soy meat burgers impact their categorization. Koreans also assessed the average of the vice and virtue and found vice-virtue combination meals healthier than the vice alone. This affects how calories and sodium are perceived. This study also shown that high virtue affects averaging bias more than weak virtue in meals with vice and virtue combo.

This study extended food categorization and averaging bias to non-US consumers and confirmed this contradictory meal choice is universal. Health halo also affects food health perception. The results of this study revealed that Koreans consider traditional food healthier than western junk food. Korean customers incorrectly assume soy meat burgers have fewer calories and sodium than regular burgers. Thus, this study explains Korean consumers' food health misconceptions related to paradoxical consumption.

This paper aims to examine how emotions affect consumers' food choices and food preparation activities during stressful periods, using the context of the coronavirus disease 2019 (COVID-19) outbreak in China.

This study used an online survey, with a sample of 1,050 individuals from 32 regions in China. Multi-regression and mediation models were used to test the relationships among perceived knowledge, emotions and food behaviors.

The results show that positive emotions positively affect healthy food consumption and engagement in food preparations. In contrast, negative emotions contribute to an increase in indulgent food consumption and quick-and-easy meal preparations. Increased knowledge of the current situation can enhance positive emotions and thus promote healthy food behaviors. Lacking knowledge may result in unhealthy food behaviors through negative emotions.

This study contributes to the understanding of emotions and food behaviors by examining the effects of both negative and positive emotions in the general population, exploring a wider constellation of food behaviors and identifying perceived knowledge as an important antecedent to emotions' effects on food behaviors. Implications for consumers and public policy are offered.

The growing number of Muslim consumers pursuing a lifestyle of health and sustainability (LOHAS) under the conditions of the COVID-19 pandemic is interesting to assess; however, existing research focusing on this topic remains scarce. This study aims to address the research gaps and add to the body of knowledge from previous literature related to Islamic religiosity, environmental knowledge, LOHAS and Muslim customer well-being.

The sample used in this study is Muslim customers, including university students in a medical department and medical workers in Indonesia, using proportional random sampling methods with a total sample of 308 respondents.

The results demonstrate that Islamic religiosity positively and significantly impacts environmental knowledge, LOHAS and Muslim customer well-being. Similarly, environmental knowledge positively and significantly influences LOHAS, and subsequently, LOHAS fruitfully impacts Muslim customer well-being.

The results can assist managers of eco-friendly and healthy products or services and public policymakers in their effort to enhance LOHAS, particularly for Indonesian Muslim consumers to accomplish well-being considering their Islamic religiosity.

The results of this study help society protect a sustainable environment by increasing their environmental knowledge and LOHAS. Based on Islamic religion, society recognize how important environmental issues are to keep the environment safe in the future and build the culture of LOHAS to achieve their well-being.

This study contributes to the body of marketing literature for Muslim green consumer behaviour in particular and the LOHAS of the Muslim customer segment based on Islamic religiosity.

This study examines the organic food continuance behavior (OFCB) of young (Generations Y and Z) Bangladeshi consumers as a part of green consumption for sustainable development. Based on the extended “Theory of Planned Behavior” (TPB), this study investigates the reasons for continuing organic food (OF) consumption. This research aims to create a model highlighting the characteristics influencing Bangladeshi consumers to continue eating OFs while considering the moderating role of health consciousness during the COVID-19 health crisis (CHC).

This is a longitudinal study, the first phase of which was conducted in 2020, whereas the second phase of data collection is completed on December 31, 2021. Thus, a longitudinal research design (N = 196) was used to investigate whether TPB element have the same impact over the period of time in two data collection phases. It also attempted to reveal if there is any change in the level of influences of Knowledge of organic food health benefit (HAK), and health consciousness on OFCB. A structured questionnaire was used to collect data from the participants of Generations Y and Z. Partial least square structural equation modeling validates the proposed research model.

Research results of phase two ensure that out of the five direct hypotheses related to social norm (SNRM), attitude (ATD), perceived behavioral control (PBRC), HAK and CHC, four (ATD, PBRC, HAK and CHC) significantly influence OFCB of Bangladeshi consumers. SNRM has no significant statistical influence on OFCB. On the other hand, all the direct hypotheses, including SNRM, were accepted during the first phase of the study. Hence, when people begin eating OF and recognize the health benefits, their firm behavioral control ensures that what others think has no significant influence on OFCB.

Most of the data for this study came from those born after 1980, commonly known as Generations Y and Z. Thus, including more data from different age groups may result in different research conclusions. The survey contains a large proportion (62%) of respondents with an income of less than BDT 40,000 per month, a price-sensitive demographic in Bangladesh. The price of OF was not included in this study though price sensitivity may have impacted the study’s findings.

This research used one moderating and four exogenous variables to determine Bangladeshi consumers’ OFCB. HAK and PBRC are proven to be the strongest determinants. Though health consciousness, Knowledge and self-control are essential, Bangladeshi citizens’ awareness of OF and sustainable consumption is still far below compared to other countries. Consequently, this study urges policymakers to raise health awareness through various social efforts.

The Bangladesh government has various initiatives to encourage sustainable development, including promoting OF consumption. Increased OF consumption will increase demand, resulting in an enormous need for organic production. This phenomenon will benefit society as bio-fertilizers are ecologically benign, resolving soil fertility issues and reducing disease risks while enhancing nutritional content. This study can serve as the foundation for developing a plan to boost the consumption of OFs, which can have a beneficial social impact.

Since no longitudinal study to explain the continuance of OFs has been observed in Bangladesh, this research uniquely contributes to predicting sustainable consumption behavior.
